Compared with the conventional glass bead, sea sand and carborundum filtering materials, the service life of the filtering material made of the metal sand is prolonged by more than 3 times, and the use of auxiliary materials (a filter screen, a gasket and the like) related to the component, the cost for cleaning the component, the labor loss, the capacity loss and the like are reduced; 2. the broken filament and the end breakage rate of spinning are reduced, the irregular concave-convex sharp characteristics of the metal sand are incomparable to those of the conventional filtering material, the metal sand is high in acute angle hardness and is not easy to deform even under the pressure of 40MPA, bubbles in a melt can be well punctured in the filtering process, foreign matters and condensed particles are blocked, and the filtering precision is improved; 3. the pressure of the assembly is stable, the boosting process is slow and stable, the production fluctuation and the unstable quality caused by the unstable pressure are avoided, and the metal sand can not change the shape along with the change of the pressure and the temperature of the melt; 4. the uniformity and spinnability of the melt are improved, and the metal sand is a good thermal conductor and can ensure that the temperature of the high-temperature melt in the assembly sand bin is uniform; 5. the chemical property is stable, and adverse reaction with the polyester melt is avoided; 6. the use is convenient, and the cleaning and drying are not needed like glass beads, sea sand and carborundum; 7. the aperture and porosity can be controlled, and the material is resistant to thermal shock, high temperature, low temperature and the like.

Therefore, the use of metal sand as the filtering material plays an important role in improving the quality of the fiber and the efficiency of chemical fiber production! At present, in the actual operation process, the metal sand used by the spinning assembly each time needs to be quantified, the metal sand is used by about 50-300g for one time conventionally, according to the process requirements, for example, 200g, 150g and the like are used for one time at present, but the error needs to be controlled to be about 3g, and the process pressure and the like are obviously influenced if the error is larger or smaller, so that the filtering effect and the spinning quality are possibly influenced. For the weighing of metal sand, the conventional operation is that a measuring cup is manually used for loading the metal sand and then the metal sand is weighed, but the method is time-consuming and labor-consuming and has larger deviation due to manual operation errors. At present, quantitative discharging is carried out by adopting the existing automatic discharging device, but the following defects still exist: 1. the degree of automation is not high, and manual semi-automatic operation is still needed; 2. due to the particularity of the metal sand, for example, a single particle is heavy, and the quality deviation is large easily caused by poor discharging control; and so on.

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

The invention will be further explained with reference to the accompanying drawings: referring to fig. 1 to 22, this example provides a metal sand weighing and loading machine for chemical fiber production, which includes a base 1, a sand supply mechanism 2 disposed on the base 1 for releasing metal sand, a cup supply mechanism 3 for intermittently supplying sand cups 5 carrying metal sand, and a weighing mechanism 4 for weighing the sand cups 5 and the total weight of metal sand in the sand cups 5.

Referring to fig. 1 to 3, which show the overall schematic structure of the loader in this example, the sand supply mechanism 2, the cup supply mechanism 3, and the weighing mechanism 4 (since the weighing mechanism 4 is under the sand supply mechanism 2 and hidden beside the cup supply mechanism 3, the weighing mechanism 4 is not visible in the overall schematic diagrams of fig. 1 to 3 due to the requirement of cooperation of the three and the requirement of a simplified structure, etc., and the weighing mechanism 4 will be described in detail in other figures below) are all disposed on the base 1.

In this example, referring to fig. 4 to 8, the sand supply mechanism 2 in this example includes at least one group of shakeout assemblies and a discharger that cooperates with the at least one group of shakeout assemblies to discharge materials into the sand cup 5;

the shakeout assembly comprises a metal sand carrier 211, and a metal sand feeder arranged below the metal sand carrier 211, wherein the metal sand feeder comprises a metal sand feeding guide groove 2121 arranged below a discharge hole of the metal sand carrier 211, a vibrator 2122 (preferably a straight vibration vibrator) arranged at the bottom of the feeding side of the metal sand feeding guide groove 2121, and a left barrier sheet 2123 and a right barrier sheet 2124 which are respectively arranged at the discharge side of the metal sand feeding guide groove 2121, and the left barrier sheet 2123 and the right barrier sheet 2124 form a directional flow-limiting gap for the metal sand to pass through;

the discharging device comprises a sand receiving hopper 221 arranged below the directional flow-limiting gap, a discharging valve body 222 communicated with a discharging port of the sand receiving hopper 221 and provided with a discharging through hole 2221 inside, and a discharging rotating shaft 223 capable of rotating relative to the discharging through hole 2221 and used for closing or conducting the discharging through hole 2221, wherein a guide hole 2231 matched with the discharging through hole 2221 to realize conduction of the discharging through hole 2221 is formed in the discharging rotating shaft 223.

Referring to fig. 4 or 5, the shakeout assemblies in this example are provided with 2 sets, the discharger is provided with 1 set, and the discharge ports of the metal sand feeding channels 2121 of the shakeout assemblies in 2 sets are all arranged above the sand receiving hopper 221 of the discharger, so that the metal sand can directly flow into the sand receiving hopper 221 from the directional flow-limiting gap and is guided downwards into the sand cup 5 through the discharging through hole 2221.

Specifically, in this embodiment, an included angle between the extending direction of the metal sand feeding guide slot 2121 and the horizontal direction is less than 5 °, so that the speed or amount of the metal sand flowing into the metal sand feeding guide slot 2121 and introduced into the sand receiving hopper 221 can be controlled, specifically, the metal sand feeding guide slot 2121 is inclined downward toward the sand receiving hopper 221, but the inclination angle is controlled, so that the metal sand moves toward the sand receiving hopper 221 under the operation of the vibrator 2122 as much as possible, and the discharging speed of the metal sand can be controlled by controlling the vibration frequency of the vibrator 2122, thereby further ensuring the discharging accuracy of the metal sand.

In this example, referring to fig. 6, the left blocking piece 2123 includes a left blocking piece fixing portion 21231 fixedly disposed on the metal sand feeding guide slot 2121, and a first bendable portion 21232 integrally formed with the left blocking piece fixing portion 21231, the right blocking piece 2124 includes a right blocking piece fixing portion 21241 fixedly disposed on the metal sand feeding guide slot 2121, and a second bendable portion 21242 integrally formed with the right blocking piece fixing portion 21241, the first bendable portion 21232 and the second bendable portion 21242 form a directional flow-limiting gap, the first bendable portion 21232 and the second bendable portion 21242 are disposed to adjust the opening size of the discharge opening, i.e., the directional flow-limiting gap, thereby controlling the discharging speed and ensuring more uniform discharging, avoiding the phenomenon that more metal sand falls to the sand receiving hopper 221 at a single time to cause the excessive metal sand in the sand cup 5, and the feeding mode of the vibrator 2122 is combined, so that the uniformity and controllability of metal sand feeding are well realized.

In this example, referring to fig. 6, the directional flow-restricting gap gradually becomes smaller in width in the direction from the feed side to the discharge side; if the arrangement is reversed, on the one hand, metal sand may be accumulated in the gap formed between the bent portion (i.e., the first bendable portion 21232 and/or the second bendable portion 21242) and the metal sand feeding guide 2121, and on the other hand, the bent portion may be deformed by the metal sand during the operation, and thus the function of controlling the flow rate of the metal sand may be lost.

In this example, as shown in fig. 1, 4, 5 and 7, the metal sand bearing container 211 includes a straight barrel 2111 with a cylindrical upper portion, a funnel 2112 with a lower portion integrally formed or fixedly connected with the straight barrel 2111, a ring-shaped magnet 2113 detachably sleeved on a feed opening of the funnel 2112, and a support connection boss 2114 formed at a lower end portion of the straight barrel 2111, a handle 2115 for gripping is provided on an outer wall of the straight barrel 2111, and the feed opening of the funnel 2112 faces the metal sand feeding guide slot 2121, which can be conveniently taken up and placed, thereby facilitating the addition of metal sand and realizing stable placement; the sand supply mechanism 2 further comprises a cylindrical support barrel 23 for supporting the metal sand bearing container 211, the metal sand bearing container 211 is erected on the cylindrical support barrel 23 through a support connection boss 2114, at least one opening is formed on the cylindrical support barrel 23, and the metal sand feeding guide slot 2121 penetrates through the opening.

Specifically, the ring magnet 2113 in this embodiment may be sleeved on the feed opening of the funnel 2112 when the metal sand carrying container 211 is taken up and metal sand is added, so that the metal sand may be enclosed in the metal sand carrying container 211 by magnetic force; when the metal sand carrier 211 is placed on the cylindrical support barrel 23 and discharged, the metal sand carrier can be manually taken out (for example, the metal sand carrier can be operated through other openings on the cylindrical support barrel 23), and the metal sand can flow out from the inside under the action of gravity; meanwhile, in this embodiment, the discharge opening of the hopper 2112 is close to the bottom of the metal sand feeding guide groove 2121, and a gap for the metal sand to flow out is reserved, the size of the gap is suitable for the situation that the discharge opening can be automatically blocked when the vibrator 2122 does not work and the metal sand is static, and the discharge can be continued after the vibrator 2122 works and the metal sand which originally exists moves away.

In this example, referring to fig. 6 and 8, the blanking rotating shaft 223 penetrates through the blanking through hole 2221, the extending direction of the blanking rotating shaft 223 is perpendicular to the extending direction of the blanking through hole 2221, and the diameter of the blanking rotating shaft 223 is greater than that of the blanking through hole 2221; the arrangement mode is that the blanking rotating shaft 223 is driven to rotate by the blanking rotating shaft driving part 224224 and the conduction and the closing of the blanking through hole 2221 are realized in the rotating process, and the blanking rotating shaft 223 is provided with the guide hole 2231, namely, the blanking purpose is realized when the blanking rotating shaft 223 rotates until the guide hole 2231 is overlapped with the blanking through hole 2221, when the blanking rotating shaft 223 rotates to other positions, for example, the guide hole 2231 is half overlapped with the blanking through hole 2221, the blanking speed is obviously slowed down, and when the blanking rotating shaft 223 continues to rotate and rotates until the guide hole 2231 is completely staggered with the blanking through hole 2221, the purpose of closing the blanking through hole 2221 is realized; the arrangement combines the mode of controlling discharging by the vibrator 2122 for vibrating discharging and the left and right barrier sheets 2123 and 2124, and at least organically combines the speed, the uniformity and the controllability of the discharging in a triple mode, so that the sand supply mechanism 2 can timely and accurately stop feeding according to a signal given by the weighing mechanism 4 in the process of releasing the metal sand, the weight of the metal sand in the sand cups 5 is ensured to be in accordance with expectation, the weighing and loading machine in the embodiment can realize that the error of the weight of the metal sand in each sand cup 5 is within +/-3 g, and finally the stability and the excellence of the spinning quality are ensured.
